Re: A memory interface burns a *lot* of power for
a mobile chip because it generally doesn't scale down in
frequency with the CPU and it never scales down in voltage.
Glad you brought that up.
Really! Delighted!
With every access to main memory Banias has to burn power from:
CPU to chipset
chipset to RAM
RAM to Chipset
Chipset to CPU
All at those "doesn't scale down in frequency/voltage" loads.
AMD's mobile chips, OTOH, burn power from:
CPU to RAM
RAM to CPU.
Thanks again for focusing our attention on that!
